Lauren – who has lost four stone – strutted her stuff in a small minidress with sexy over-the-knee boots and a leather jacket.

Speaking about her return to the show which made her famous, Lauren said: "I shot my scenes last Friday and I was actually really nervous about it. I can’t reveal too much, but I had a right laugh with the TOWIE crew and people I filmed with."

The star can't wait to be back though, and revealed: "I was really excited, especially as I look quite different to when I was last on the show. I can’t wait for you to see it later this month."

Her TV news coincides with the announcement she has a fitness DVD out - Lauren’s OMG! Workout.

"Oh my god, I needed to lose weight. At my biggest, I was huge. I tried for years to lose it but nothing worked," she revealed in the DVD.

"But this system's done it for me. I lost four stone and dropped five dress sizes."
